Cast Alum Substitute from NACO 150
Cast Alum Substitute from NACO 150
(OP)
I have two Norwegian items cast from NACO 150 Alum (Nordisk Alum Co.), circa 1971. American sub given is SAE 309.
We have no molds to remake just one of each part. I'm looking for an extruded substitute alum alloy for the cast alum material and make billet from a block about the size of a 3 lb. coffee can.
This would be the easiest route because of reduced paperwork and recertification, i.e., a direct replacement material. If items were made from sheet alum and welded together, recertification would be in the process again.
Thank you for reading and your suggestions.

Documentation wise, how would I get there?
